Trends in middle - and upper - level
tropospheric humidity from NCEP reanalysis
data
It is arguably time to tackle the
tropospheric humidity issue, but this should be done from the perspective of comparing multiple
data sources and assessing the uncertainty, before publishing trend analyses in the context of saying something about climate change.
«Trends in middle - and upper - level
tropospheric humidity from NCEP reanalysis
data» by Garth Paltridge, Albert Arking and Michael Pook
On Feb 26, Garth Paltridge, Albert Arking and Michael Pook's report on a re-examination of NCEP reanalysis
data on upper
tropospheric humidity was published online by Theoretical and Applied Climatology.
I do not know the accuracy of the NCEP reanalysis
data on upper
tropospheric humidity, but the direct measurement of
humidity by weather balloons seems preferable to the very indirect determination from satellite
data.
Apropos of which, in the specific context of long - term trends in
tropospheric humidity, it seemed to us that an advantage of the NCEP re-analysis over other re-analyses (over ERA 40 for instance) is that it does not complicate the issue by introducing various types of satellite
humidity data into the record as they become available.
The National Centers for Environmental Prediction (NCEP) reanalysis
data on
tropospheric humidity are examined for the period 1973 to 2007.
